Daiwa Securities, an Asian financial services firm, Japan’s second largest securities brokerage, provided a screenshot of the leaked calendar from San Francisco’s Moscone Center, hinting that the event could take place between June 10 and June 15.

In addition, the blog MacOtakara announces that the iPad 3 will be unveiled in March during a presentation organized by Apple.

As for the iTV, DigiTimes reports that Apple is unlikely to release the rumored Apple-branded TV in 2012.

Citing “sources in Apple’s supply chain,” the website wrote Friday that Sharp, the company rumored to provide display panels for the iTV, isn’t ready to ship the IZGO (indium gallium zinc oxide) display panels that Apple plans to use for its device.

This means that the release date of the iTV could be pushed to the second half of the year.

The introduction of the iTV is seen by many as a major leap for Apple. The device is rumored to feature apps and voice controls powered by Siri.
